## Summary
Surfaces the `label_on` and `label_off` (aka `on`/`off`) props for
BOOLEAN widgets in the Vue implementation using a new Reka UI
ToggleGroup component.
**Before:** Labels extended outside node boundaries, causing overflow
issues.
**After:** Labels truncate with ellipsis and share space equally within
the widget.

## Changes
### New ToggleGroup Component (`src/components/ui/toggle-group/`)
- `ToggleGroup.vue` - Wrapper around Reka UI `ToggleGroupRoot` with
variant support
- `ToggleGroupItem.vue` - Styled toggle items with size variants
(sm/default/lg)
- `toggleGroup.variants.ts` - CVA variants adapted to ComfyUI design
tokens
- `ToggleGroup.stories.ts` - Storybook stories (Default, Disabled,
Outline, Sizes, LongLabels)
### WidgetToggleSwitch Updates
- Conditionally renders `ToggleGroup` when `options.on` or `options.off`
are provided
- Keeps PrimeVue `ToggleSwitch` for implicit boolean states (no labels)
- Items use `flex-1 min-w-0 truncate` to share space and handle overflow
### i18n
- Added `widgets.boolean.true` and `widgets.boolean.false` translation
keys for fallback labels
## Implementation Details
Follows the established pattern for adding Reka UI components in this
codebase:
- Uses Reka UI primitives (`ToggleGroupRoot`, `ToggleGroupItem`)
- Adapts shadcn-vue structure with ComfyUI design tokens
- Reactive provide/inject with typed `InjectionKey` for variant context
- Styling matches existing `FormSelectButton` appearance
Fixes COM-12709
